DISTRIBUTING ELEVATOR.

Application filed May 26, 1920. Serial No. 384,358.

To all whom it may concern-.-

Be it known that I, WALTER J. BLnNKo, a citizen of the United States,and resident of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in DistributingElevators; and I do hereby declare the fol lowing to be a full, clear,and exact description thereof,

My invention relates to elevators for use in loading apparatus and thelike. and it has special reference to elevators of the type which areadapted to lift material from a common source and deliver it into anyone of a number of receptacles, and which for this purpose are providedwith a swivel mounting around which the elevator may be turned in thearc of a circle.

The object of my invention is to provide an improved swivel mounting forelevators of the above-indicated character and, in particular, toprovide a mounting which shall be simple and rugged in construction andwhich shall serve to support the elevator from a point above its lowerend, for a purpose more fully described below.

In the accompanying drawing, Fig. 1 is a side view partly in elevationand partly in section of an elevator constructed in accordance with myinvention; Fig. 2 is an enlarged detail showing in vertical section theswivel mounting which I prefer to employ, and Fig. 8 is a plan view ofthe construction shown on Fig. 1.

In the drawing, the numeral 2 designates a pit which is below the groundlevel 3 and in which is disposed the lower end of an endless bucketconveyer t of any suitable construction. The conveyer l is carried upona supporting frame comprising inclined supporting members 5, verticalbraces 9 and a truck structure 20. The inclined members 5 also carry ahopper 6 that is adapted to receive material from a feeder 7, thespecific construction of which forms no part of my present invention,and which is located beneath tracks 8. The braces 9 carry at their lowerends wheels 10 that travel on a circular track 12 centered at 16.

Extending on either side of the feeder 7 are two channel beams orsupports 13 which are bolted to the foundation 14 and which converge attheir inner ends 15 to support the swivel mounting for the elevator,which is designated generally by the numeral 16 and is shown in detailin Fig. 2. This mounting consists of a plate 17 having a sphericallycurved depression 18 on which rests a swivel member 19 carried on theunderside of the truck structure 20 the arms of which extendhorizontally between the swivel mounting and the lower ends of thesupporting braces 9. The spherical bearing ensures freedom of motion ifthe track 12 is irregular. The plate 17 and the swivel member 19 aresecured together by means of a loose-fitting hollow bolt 21 throughwhich may extend the lead-wires for the driving motor of the elevator.Theconveyor frame 5 is supported by the braces 9 and by a transverse bar22 which extends across the truck frame 20.

When the above-described elevator is in operation, the materialdischarged into the hopper 6 by the feeder 7 is carried upward by theelevator buckets and discharged into one of the bins or otherreceptacles that may be arranged adjacent to the curved track 12. Byreason of the fact that the swivel mounting is located above the lowerend of the conveyor, it will be apparent that the pit 2 need only bedeep enough to provide clearance for the elevator buckets. This is aspecial advantage owing to the fact that no obstruction whatever existsat the lower end of the elevator, as compared with distributingelevators in which the conveyer-supporting frame is mounted on a swivelin the pit and beneath the lower end of the elevator. Also the mountingcannot freeze in winter.

Vhile I have shown and described herein a preferred form for employingmy invention, it is to be understood that various changes may be made inthe form and ar-' rangement of parts, and I therefore desire that nolimitations be imposed upon my invention except such as are indicated inthe appended claims.

YVhat I claim is:

1. A distributor elevator comprising a conveyer-supporting frame mountedto swing pivotally, a conveyer carried by said frame, a feeder disposedadjacent to said frame, and a pivot bearing for the said frame disposedabove the lower end of said conveyer and on the side of said conveyertoward said feeder.

2. A distributing elevator comprising a c-onveyer-supporting framemounted toswing pivotally, a conveyer carried by said frame, amaterial-receiving hoppercarried by the said frame and a pivot "bearingfor the said frame disposed above the lower end of said conveyor and onthe same side of said conveyer as said hopper;

3. A distributing elevator comprising a conveyer-supporting framemounted to swing pivotally, a conveyer carried by said frame, a curvedtrack formingasupport for the outer end of the said frame, and a pivotbearing for the said frame disposed above the lower end of said conveyerand on the opposite side of said frame from said track.

4. A distributing elevator comprising a ronveyer-supporting framemounted to swing pivot-ally, a conveyer carried by said frame, a hoppercarried by the said frame, a curved track forming a support for theouter end of the said frame and a pivot bearing for the said framedisposed above the lower end of said conveyer and on the opposite sideof said frame from said track.

5. A distributing elevator comprising a frame having inclined supportingmembers, an endless conveyer carried by said supporting members, andadapted to be charged from the upper side thereof, and a pivot positionfor all angular positions of thesaid frame.

7. A distributing elevator comprising two stationary supports, a pivotbearing carried by said supports near the junction thereof,

a curved track, an inclined conveyer-supporting frame supported partlyby saidv bearing and partly by said track, an endless conveyer carriedby said frame, and a hopper carried by said frame beneath the saidbearing.

In testimony whereof I, the said lVAI/rnr. J, Br-nNKo, have hereunto setmy hand.
